i had a similar post a few days back http://www.blasterforum.com/engine-13/please-help-whats-best-blaster-exhaust-system-20162/ ........ i had decided on a shearer system. I am almost exclusively a trail rider putting around woods looking for the next hill to attempt to climb. I did come across a fmf sst set tho for $40 and picked it up. Worth putting on the bike til i get the shearer or just resell to the next guy who thinks he's getting a bargain?
